An aquarium has received a surprise of seven baby stingrays born to mothers who have not been near a male for two years.
Staff at the Sea Life London Aquarium noticed two female stingrays looking bloated and were surprised to discover they were both expecting young.
Seven six-inch baby stingrays were born to the two mothers, and are now big enough to be moved to their new home in the aquarium's SOS area.
Paul Hale, head curator at the aquarium, said: "Rays have been known to store sperm and not give birth until they decide the timing is right, but it's not something I've seen before in my eight years at the aquarium.
"The staff noticed two female stingrays looking bloated so gave them a health check and were surprised to discover they were both expecting, considering there have been no males in their display for so long."
He added: "Rays are already one of the most popular creatures at the aquarium so these pups will be very popular with our visitors this summer."
